Abstract: Building decoration is the final stage of building completion, which can enhance the overall functionality and aesthetic value of the building. Traditional construction techniques may have limitations in meeting people's growing needs due to technical restrictions. Therefore, some new technologies need to be introduced to overcome these challenges, improve the efficiency and precision of construction, reduce costs, and promote its development towards green environmental protection, personalization and artistic design innovation. The EPC engineering model fully mobilizes the initiative of construction units in developing new productive forces.
